Chiefly, it was my ignorance of that RFC that caused me to overlook it
:) Now that I look at it, it's rather difficult to reconcile it with
Gnus.  The URL has a lot of information built-in that in Gnus is
associated with the server name.  So I should ignore that part of the
RFC and just do

imap://minbari.org/storage?SUBJECT%20filename

passing the filename as a subject string search, and

imap://minbari.org/storage?UID=20

for direct access to articles.

Something like this is probably good enough, and I'd rather let
imap.el worry about the best authenticator.  Does that sound OK?

Supporting the full syntax is way too much work for something that
Gnus already does internally.  If anyone wants to work on supporting
the full URL scheme and create an ephemeral server on the fly to
retrieve a message, they're welcome :)

Sorry, I should have been clearer.  I understand about local scope, I
just don't know which variables to save before entering another group
temporarily.  But I think this won't be a problem if I use imap.el
instead of nnimap.el.
